Щоб обчислити вираз, розділимо його на кілька кроків:
12¼ : 25 = 0,49

14,5 · 0,8 = 11,6
Додамо результати попередніх операцій і додамо 75: 0,49 + 11,6 + 75 = 86,09
Помножимо результат на 0,0125: 86,09 * 0,0125 = 1,075125
Нарешті, додамо 1,075125 до добутку 80 і 3: 1,075125 + (80 + 3) = 84,075125
Отже, результат виразу дорівнює приблизно 84,075125.
